Time travel, I came to the future world of the 24th century, and saw the new life of human future.
Is the future house mobile or free to live in. There are not many furniture and electric appliances, but they have complete functions. The air conditioner is gone. The room is warm in winter and cool in summer. It turns out that people store the hot air in summer for use in winter, and store the cold air in winter for use in summer. There is no lampblack machine in the kitchen, because the new cooking oil will not produce lampblack to pollute the environment. There is no lamp. Advanced lighting materials are shrunk into small particles. You can put them into environmental protection paint and paint them on the wall. When the light is dark, the wall will produce light. People can adjust the brightness manually. The TV no longer needs remote control switch. As long as you say "on", it will start to play, and can provide different programs for different people at any time. It really becomes "Green TV". Children can watch healthy programs.
In the future, the world's cars will be very environmentally friendly. They will all become solar powered cars. The exhaust emissions will still be beneficial to human life. Cars can be changed into various forms, driving on land, sailing on the sea, flying in the sky. In this way, it is much more convenient for people to travel.
How environmentally friendly and comfortable life will be in the future!
